Students in Ms. Winters' class were interested in testing the antibacterial strength of hand soap versus hand sanitizer. The students planned to wash their hands using the sanitizer or soap and warm water for two minutes, then dry their hands with a paper towel. The standard of comparison would be rubbing their hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands would be swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures would be counted. What would be an appropriate research question to guide this scientific investigation

Is hand sanitizer more effective in killing bacteria than hand soap?

Explanation:

The most appropriate question will be questioning the effectiveness of the hand sanitizes versus soap.

The students compared the effectiveness of both the chemicals. The children must use soap and then their hand must be used as an area to get sample for microbes.

Then another group of children will use soap for washing the hand and then use hand as an area to take sample for the microbes.

The plate will show the number of colonies which will decide the effectiveness of the soap or sanitizer.

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
